PREFACE

This document is Part 11 of the official compilation and publication of the adoptions, amendments and repeal ofregulations to California Code of Regulations, Title 24, also referred to as the California Building Standards Code.This Part is known as the California Green Building Standards Code.

The California Legislature delegated authority to various State agencies, boards, commissions and departments tocreate building regulations to implement the states statutes. These building regulations have the same force of lawand take effect 180 days after their publication unless otherwise stipulated. The California Building Standards Code

applies to all occupancies in the State of California as annotated.

A city, county or city and county may make necessary changes to the provisions contained in this code which arereasonably necessary because of local climatic, geological, or topographical conditions. Findings of the localcondition(s) and the adopted local building standard(s) must be filed with the California Building StandardsCommission to become effective and may not be effective sooner than the effective date of this edition of theCalifornia Building Standards Code. Building standards that were adopted by local ordinance and applicable toprevious editions of the California Building Standards Code do not apply to this edition without appropriate adoptionand the required filing.

EFFECTIVE USE OF THIS CODE

This format of this code is common to other parts of the California Building Standards Code and contains buildingstandards applicable to occupancies which fall under the authority of different state agencies. Occupancies andapplications under the authority of a specific state agency are identified in Chapter 1, Sections 103 through 106.

Sections of this code which are applicable and adopted by each state agency are identified in the ApplicationChecklist for each state agency contained in Chapter 11. The following outline may be helpful as a guide to establishwhich provisions are applicable to a specific occupancy.

1. Establish the type of occupancy.2. Verify which state agency has authority for the established occupancy by reviewing the authorities list in Sections103 through 106.3. Once the appropriate agency has been identified, find the application checklist for that agency in Chapter 11.4. The application checklist will list the green building measures adopted, provide the effective date and otherinformation regarding each green building measure applicable to the established occupancy.5. Each green building measure listed in the application checklist has a section number which correlates with asection number in Chapters 4 through 8.6. More information is available for each green building measure listed in the application checklist in the correlatedsections contained in Chapters 4 through 8.

CHAPTER 8

ENVIRONMENTAL QUALITY

SECTION 801GENERAL

801.1 Scope. The provisions of this chapter shall outline means of reducing the quantity of air contaminants that areodorous, irritating, and/or harmful to the comfort and well-being of a buildings installers, occupants, and neighbors.



AGRIFIBER PRODUCTS. Agrifiber products includewheatboard, strawboard, panel substrates and door cores, notincluding furniture, fixtures and equipment (FF&E) not considered base building elements

COMPOSITE WOOD PRODUCTS. Composite wood products include hardwood plywood, particleboard, andmedium density fiberboard. Composite wood products does not include hardboard, structural plywood, structuralpanels, structural composite lumber, oriented strand board, glued laminated timber as specified in Structural GluedLaminated Timber (ANSI A190.1-2002) or prefabricated wood I-joists.

HVAC UNITS, SMALL. Those containing less than 0.5 lbs of refrigerant.

INTERIOR, BUILDING, The inside of the weatherproofing system.MERV. Filter minimum efficiency reporting value, based on ASHRAE 52.2-1999.

MOISTURE CONTENT. The weight of the water in wood expressed in percentage of the weight of the oven-drywood.

MULTI-OCCUPANT SPACES. Indoor spaces used for presentations and training, including classrooms andconference rooms.

SINGLE OCCUPANT SPACES. Private offices, workstations in open offices, reception workstations, and ticketbooths.

VOC. A volatile organic compound broadly defined as a chemical compound based on carbon chains or rings withvapor pressures greater than 0.1 millimeters of mercury at room temperature. These compounds typically containhydrogen and may contain oxygen, nitrogen and other elements. See CCR Title 17, Section 94508(a).

SECTION 803FIREPLACES

(Reserved)

803.1 Install only a direct-vent sealed-combustion gas or sealed wood-burning fireplace, or a sealed woodstove, andrefer to residential requirements in the California Energy Code, Title 24, Part 6, Subchapter 7, Section 150.

SECTION 804POLLUTANT CONTROL

804.1 Indoor air quality (IAQ) during construction. Maintain IAQ as provided in Sections 804.1.2 and 804.1.3.

804.1.2 Temporary ventilation. Provide temporary ventilation during construction in accordance with Section 121of the California Energy Code, CCR, Title 24, Part 6, and Chapter 4 of CCR, Title 8, and as follows:

1. Ventilation during construction shall be achieved through openings in the building shell using fans to produce

a minimum of three air changes per hour.2. During dust-producing operations, protect supply and return HVAC system openings from dust.3. The permanent HVAC system shall only be used during construction if necessary to condition the building

within the required temperature range for material and equipment installation. If the HVAC system is usedduring construction, use return air filters with a Minimum Efficiency Reporting Value (MERV) of 8, based onASHRAE 52.2-1999, or an average efficiency of 30% based on ASHRAE 52.1-1992. Replace all filters withMERV 13 filters by Section 804.2.3 immediately prior to occupancy.

4. If the building is occupied during demolition or construction, meet or exceed the recommended ControlMeasures of the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) IAQGuidelines for Occupied Buildings under Construction, 1995, Chapter 3.

804.1.3 Additional IAQ measures. Employ additional measures as follows:


27/60


1. When using generators to generate temporary power, use generators meeting the requirements of CCR, Title13, Chapter 9, or local ordinance, whichever is more stringent.2. Protect on-site absorbent materials from moisture. Remove and replace any materials with evidence of mold,mildew, or moisture infiltration.3. Store odorous and high VOC-emitting materials off-site, without packaging, for a sufficient period to allow

odors and VOCs to disperse.4. When possible, once materials are on the jobsite, install odorous and high VOC-emitting materials prior to

those that are porous or fibrous.5. Clean oil and dust from ducts prior to use.

804.2 IAQ post-construction. After construction ends, with all interior finishes installed, flush-out the building bysupplying continuous ventilation with all air handling units at their maximum outdoor air rate for at least 14 days whilemaintaining an internal temperature of at least 60F, and relative humidity no higher than 60%. Occupancy may startafter 7 days, provided flush-out continues for the full 14 days. Do not bake out the building by increasing thetemperature of the space. (If continuous ventilation is not possible, flush-out must total the equivalent of 14 days ofmaximum outdoor air.).

804.3 Covering of duct openings and protection of mechanical equipment during construction. At the time ofrough installation, or during storage on the construction site and until final startup of the heating and coolingequipment, all duct and other related air distribution component openings shall be covered with tape, plastic,sheetmetal or other methods acceptable to the enforcing agency to reduce the amount of dust or debris which maycollect in the system.

804.4 Finish material pollutant control. Finish materials shall comply with Sections 804.4.1 through 804.4.4.

804.4.1 Adhesives and sealants. Adhesives used on the project shall meet the requirements of the following

standards.

1. Adhesives, adhesive bonding primers, and adhesive primers shall comply with Table 804.4.1.2. Aerosol adhesives shall meet the requirements of California Code of Regulations, Title 17, commencing with

Section 94507, http://ccr.oal.ca.gov/ .

804.4.2 Paints and coatings. Architectural paints and coatings shall comply with Table 804.4.2.
